It's possible. But it would be an incredibly strange thing to do over some charges that really aren't a big deal, especially when they happen so young in life. I know a ton of people who have had MIP's and minor drug possession charges in their late teens that caused them no real issues in life. It would be far easier to ride out the punishment than it would be to completely abandon your life, your friends, family, live in hiding, assume a new identity that is actually viable, try not to avoid the law (especially if you're a person who likes to break it sometimes), etc. I can entertain the possibility that she might be 'reinventing' herself, but the legal reasons wouldn't possibly be the ultimate motivation, would they? It would have to be something far more extreme, I would think. Although anything is possible if she is seriously mentally ill (she's right around the age that some of those illnesses usually begin, after all).
