sure it can, and IIRC there are projects doing this.
To make this work regardless of how code makes it's way to the
compiler, hook up to lua_load or the lzio stuff (in 5.0.2).

For most applications it should suffice to run mylang.lua
with scriptname.mylang as arg and in mylang either bypass
the require-module mechanism altogether or pimp it up
using some of the fallback mechanism discussed recently.

Do not expect this to become the default behaviour of
the lua binary as shipped. It's just too easy to make a
mylang binary.

As most luas are running as part of some application anyway,
it is quite fashionable to customize lua to any personal taste
and generate lua code on or the other way.
