OCs are allowed to interact with big canon characters like headmasters and teachers, who typically interact with many of their students. I'm guessing Glenn the Grimm Dragon follows the same rule, considering that all who participated in the Battle of Beacon would have seen it, though it's unlikely that anyone outside of Ruby interacted with it much.

Unless the OC is super knowledgeable about Grimm or something, I'd say they shouldn't know of the Dragon's existence. Even then it's a little questionable, and they should definitely not know exactly where it was hiding/sleeping. But they can know a bit about what it is.
