Claims of compatibility is one area of Trademark law where you can get into
trouble.  A claim of "100%" compatible with D20 is pretty easy (since there
are no guidelines), but a claim of 100% compatible with D&D could easily
open you up to trouble.  It would work for an adventure module, but if you
add anything new in terms of classes, monsters, spells, or the like then you
give WotC room to argue that your additions are not in fact compatible.  It
would be hard to imagine them doing so unless they didn't like the idea of a
compatibility claim.
