If you're asking if you can adapt an alternate tuned song to be played on a standard tuned guitar, sure. It probably won't sound the same as the original, but it's the same 12 notes no matter how the strings are tuned.
For instance, "Rusty Cage" by Soundgarden is in standard with the low E tuned down to B. Any of the low notes could be played two frets higher on the A string, but it's obviously not gonna be the same low octave as if it's tuned down.
The notes may be the same, but it may not be possible to play the same chords in standard tuning. A good example is Kashmir by Led Zeppelin; it's somewhat possible to play in standard tuning, but it sounds goofy because you can't really play the same chords.
Can you turn any song that uses alternative tuning into one that uses standard tuning?
NO: your fretboard doesn't have the required range of notes... ex: 7 string Drop A song with high E solos up to 24th fret AND lowA chugs --- on a 21-22 fret 6 string.

Here's a mish mash of a whole bunch of screenshots I took displaying how to play an A chord. For your own experimentation, play all of them on a clean channel just to see how different some of them can sound, even though they are all technically A chords.

In short yes -that's the beauty of a guitar and advantage over most other instruments -almost infinite permutations of voicings to interpret any song with -and simple tuning changing to move between tunings and their possible voicings in only moments.
The catch is it will not be the exact tonality or likely voicing if a different tuning is used -you may have to invert a chord voicing or arpeggio sequence to achieve the same notes in a different tuning -but that's the fun of a guitar.
That's actually the weakness of the guitar. People can alter the tunings as they wish to suit whatever the fk their music requires. It leads to more headaches than alternate musical dimension.
What’s interesting is if you detune a guitar, somehow it’s still a guitar. If you tune it completely different, it’s still a guitar.
But if you detune a violin, it’s a viola. And if you tune it completely different, it’s just out of tune and can’t be played.

Following that metaphor - which is spot on, by the way - I've actually turned a violin into a viola, and then tuned it completely different, and then it couldn't be played.
One day I realized that on a 7 string with an extended scale length, I can go to A Standard with a low E string...and now it's all the way down to low E on a bass (and yep, I used a bass string!), and all of the open chords are legit open chords...none of them are a sharp or a flat! And the tuning was weird: E-A-D-G-C-E-A...so drop the "C" string a half-step, and I've got an odd way to make a 7 string bass guitar that starts at 4 string bass low E...thus I'd be able to essentially play two different tunings: A Standard with a low E, or E Standard bass with high B-E-A strings. And I'm only giving up 7 frets at the top of standard high E...!!!
PERFECT!!!
Yeah, it doesn't work that way. All that I did was create a mud slut. If what you're looking for is pure mud at the bottom end from about maybe A under standard low E, then this is the exact recipe for THAT disaster! I was all the way up to a .90 that I mean JUST BARELY fit in that guitar (and actually kinda didn't), so I was at about 25 pounds of tension on my strings, and it was a MUD SLUT on the bottom end. The pickups AND the amp are just not tuned to that set of frequencies.
That was my first extended scale length guitar (27"), AND my first 7 string. I've since learned that A Standard is at or maybe just beyond the threshold for a guitar, and that B Standard on a 6 string is often a bit muddier than the low B note (same note, same octave) on a standard-tuned 7 string. The pickups on a 7 string were designed to deal with low B and can even handle a low A pretty nicely; while the pickups on a 6 string are done around C, and B is starting to be a reach for them. Low A becomes highly questionable.
And then we get to argue if B Standard actually does turn your violin into a viola, because now it's technically a baritone! They play like a guitar, and that's all that matters! And that's why I said that you're spot on, because in the end, it's still a guitar running guitar pickups through a guitar amp. But yeah, if you go too low, you'll hate it.
