Hmm. I couldn't say specifically, but here's what comes to mind: you're allowed to make a character who knows ponies in other cities. You're not allowed to force a relation on other characters. So, you probably couldn't make a household name (i.e. a character that everyone should have heard of), but I think you can make them reasonably famous within certain spheres. So say, a well known researcher in their field, or part of a popular underground music group or the like...
