Section 5.3 seems to cover this as well. There is only a problem if, say, you use a similar logo and similar domain name. https://meta.wikimedia.org/wiki/Trademark_policy#FAQ-fakearticle
That said, to the extent that we care about not being confused with mirrors and forks, we should perhaps consider using a well-defined customization of Vector (with some colors and other visual features that are not the same as the default MediaWiki install) on the core WM sites. Then there would be even less of a chance of any confusion; or of any possibly unintended trademark conflict.

Not having read the policy in depth, I'll say that the firefox project (for example) handles this situation by reserving trademark rights, but then granting very liberal automatic licenses to aspects of the trademark if you meet certain conditions. So one might resolve the situation with wikipedia by saying that the "appearance of the article" is trademarked, but that mirrors/offline viewers meeting certain guidelines (proper attribution? links to the source site?) get an automatic license to the trademarked appearance.
I hope that someone who is more knowledgeable about the trademark policy will tell me if i'm on the right track, or whether some other means of protecting offline readers is envisioned. --scott
