I have previously had a non-imm o visa as a dependent of a foreign spouse, and a similar situation arose. I was only able to extend the visa if my wife had already extended her visa.

It caught me out once and I had to leave, go to the consulate, get a new visa issued, and come back on a new non-imm O visa.

So, I can confirm that this is standard across visa types 🙂

I'm interested in what happens when you try this as well. I may end up in a similar situation next month 🙂 Please post a follow-up!

Thanks for the input.

I’ll make a trip over to Chaeng Watthana next week and see if I can chat with an IO about what’s possible.
