Not so certain. To get access to the preline, it needs to say pre on your boarding pass. To get access to the priority line, it needs to say priority on your boarding pass. One of the reasons this was done was precisely to avoid people turning up with what would be more exotic cards to TSA staff and argue their way into one of the lines. And I wouldn't be surprised if at an airport like Atlanta the tSA people actually are familiar with the sky team levels.
