Yes the Turkish version of the access rules indicate the same. However, I don't think you would have success entering the lounge after showing this website to the lounge dragon at the entry if you're not actually eligible. If I didn't have status I would have tried it.

Go for it; no one is stopping you. I hope you enjoy both. If you hold an Elite Plus status at that time, don't forget to add the Exclusive Lounge to your visit places at Istanbul Airport.
