As we've discussed before with Jon that - if he is
the child of Rhaegar and Lyanna - a claim to the throne would really depend on whether or not Rhaegar ever married Lyanna.
Now Rhaegar was already married to Elia of Dorne, but bigamy is something that Targaryens have indulged in in the past. If he married Lyanna Jon has a hypothetical claim, if not he's just a bastard.
Of course, Aegon - as the probably elder son of Rhaegar's first wife - has a better claim anyway. If he is indeed really Aegon, I know there are people who like to speculate he's descended from the female line of the Blackfyres (legitimized Targaryen bastards who tried twice to take the throne).
Kings can do whatever the hell they want. Stannis wants Jon to "untake" the black, so if Jon is willing it's going to happen.
Basically. Stannis has the authority to not just have Jon 'untake' the black, but also to legitimize his heritage and thus make him the default claimant on Winterfell.
..but who in authority would give a potential Targaryen claimant the right to leave the order? They'd have to both have the authority and be able to benefit - like, say, Queen Daenerys legitimizing and marrying Jon Targaryen. If not that scenario can't think of any cases it'd be useful.
