Re: "True" Tele Requirements
To be a full-on, pure Tele, to me it needs:
Tele pickups (neck and bridge)
Tele Scale length
Tele bridge (full length)
Tele body (i.e. no chambering, F holes, contours, etc.)
Maple neck (all maple or with rosewood board)
Alder or ash body
This is not to say that there is a thing wrong with anything outside of these parameters. I just wouldn't consider/call the guitar a full-on, pure Tele, i.e. I wouldn't feel right using that guitar to make generalizations about Teles in general. Sure, "back in the day," you can find bona-fide Teles that fall outside of these parameters (e.g. pine, rosewood, and mahogany bodies, or Tele Thinlines), but I wouldn't use them as an example of your standard Tele, for purposes of making generalizations about what Teles are like.
