I can't see any reason why not, but it would probably be considerably more expensive than bought tiles (it would be a special order).
It can't hurt to ask a glazing manufacturer though. Also they should certainly be able to make you a mirror to the exact size of whatever it is you want covered (instead of using tiles).
