As long as Bran returns to Winterfell, and tells Jon about his parentage, Jon can simply abdicate on the grounds that Bran is Eddard's true heir. Telling them he's a Targaryen while remaining their king won't go down well with the Northern houses, however wisely he tries to rule. By abdicating in Bran's favour, Jon doesn't even need to tell anyone he's the son of Prince Rhaegar.
