Contrary to what the answers here are expressing, I have a yellow book and a non o visa based on marriage and the yellow book suffices for a TM 30 substitute. That is my recent experience on Koh Samui. The Immigration Department in other provinces maybe different.
Yes Brandon that's 100% correct. I've just been through the process of getting a non-o and converting it to a non-o based on marriage. There was no criminal record check.
