Is it possible to buy wow token without an active sub (for balance not game time)

Hello, title says it all.
I want to buy Diablo IV with bnet balance and i want to use my gold in my inactive world of warcraft retail account. But i do not want to use 1 token to add 1 month subscription to wow just to buy wow tokens from AH which will take max. 15 minutes. Is there any way to fix this issue without subbing to wow? anyone?

you could mail/ticket and ask for 1 day playtime as you are unsure and haven’t played for a long time. Usually works.

Edit: maybe it only works for me as they see I always buy more time after…
