Copyright = is the right to own noncorporeal things pertaining to intellectual property: names, distinctive marks, words, etc.
You haven't defined copyright here. You defined trademark. If JKR had already published such a work, she might have a claim re: competition, but she has not; she wrote works of fiction, and this is clearly a companion/guidebook. She has permitted other guidebooks before. Just because she wants to write one doesn't give her the exclusive right to shut down others.
