Sure. A trademark license that's "free"--when evaluated as if it was a
copyright license, say--is probably lost, which is where the claim that
"enforcable trademarks can't be Free" comes from.
What I'm not sure about is whether, and when, this is a problem. Debian
clearly allows copyright licenses to say "if you modify this software,
change the name". What's the problem with implementing that same
restriction with a trademark (which is the "correct" way of doing it,
anyway)? It's a little more complicated, conceptually, since instead
of evaluating a work and its license, we're evaluating a work with a
name, the work's license, and the name's license, but at a high level
it doesn't seem any different.
Now, from another perspective: if Debian needs to modify Mozilla in
a way that would cause other parties (doing the same thing) to have to
rename it, Debian shouldn't be shipping it as "Mozilla" (even if special
permission is given). That means that a competing fork of Debian would
be placed at a disadvantage, having to rename packages away from their
familiar names; it feels like a DFSG#8 problem (as has been mentioned),
though exactly how isn't quite clear.
We can look at the same thing from a copyright standpoint, to avoid
having to talk about trademarks, which are somewhat less well-explored
here. A license can say "if you modify this, you must rename it". The
Debian package modifies the package, but the upstream author says
"Debian's cool, don't bother renaming it". What does Debian do? The
license--even without the special permission--is DFSG-free. The
additional permission doesn't change that. Debian can either accept
the additional permission and not rename it (but getting an "unfair
advantage against forks" in the process), or rename it anyway. What
happens?
