answer:To the best of my knowledge, it’s okay. I see something of the sort done all the time. Just don’t use any excerpts or images or borrow anything without being very sure of your ground with respect to permissions. I’m not a legal advisor, though. Here’s someone who supplies legal information (not advice), but I didn’t find your specific question among those he treats. However, I just read a novel in which there were three or four references to a well-known cartoon mouse, unnamed, and I couldn’t tell whether the author (who was free with other cultural references) was being coy or just really didn’t want to tangle with the sharp-fanged Disney legal machine.
