Will this itinerary allow me to use the TK Business Class Lounge in the International Terminal of IST?
I would hang out there a little while, then go to the Domestic terminal / area.
No, you would be unable to use the international lounges with a domestic boarding pass.
The primary issue would be that the security would not allow you to use the transfer security checkpoint without a valid onward international boarding pass.
