I'm convinced it does, for packages that are indeed released under the GNU GPL. This is not the case of fedora-logos or anaconda-images, since their license is not the GNU GPL. But then again, IANAL.

not sure it does.
I don't believe this is any different from patents. If you release GPLed code that builds upon patents you own, you cannot sue anyone for patent violation because, by the GPL, you cannot impose any further restrictions on the distribution of the software. I don't see that with trademarks this would be any different.
Hmm... On second thought, maybe this limitation doesn't apply to the copyright holder, only to redistributors? At this point, I have to claim again that IANAL and leave it at that :-)
