I'm pretty sure that doesn't really matter. There have been plenty of people that have made their names "Darth ******" something or other, so I don't really thing "Darth" holds too much meaning except for to the character that you or someone else is writing. If there's an actual Darth avatar title thing, though, I'm not sure if you can get that added unless you've completed the rank of Knight.
I don't believe you'd catch any flack for it, no, but if you did then you certainly wouldn't be punished for something like that, they'd just ask you to remove it.
