If you're asking can I do something illegally, even if that means being fined, jailed, made to pay a $1700 USD for a last-minute plane ticket (and jailed until it is paid in full), and blacklisted from the country, you can answer that yourself.
Some schools/visa agents/forum members might suggest you can, but if you get caught you can be fined—and are deported and blacklisted from the country. Look into language schools or corporate jobs. 👍
If you don't have a bachelor's degree, you can't legally teach in Thailand. So taking people's time to answer all of your questions is pointless if you don't have a degree.
