"Fair use" is a copyright thing, not a trademark thing, so it's mostly irrelevant here. It could apply to the actual SVG XML, and belong to whoever drew it, this may not be the owner of the trademark.

IANAL, but in general anyone can use a trademark to refer to the thing that is trademarked. You can't use it where it could be confusing, so you can't open a restaurant and call it McDonalds. But you can publish a book or website called "My guide to McDonalds Restaurants" as long as it really was about McDonalds.
