Yes, if you are running it no farther than 100 feet. If you are going over 100 feet use AWG # 10 wire on the 20 amp breaker.

How do you wire a 15 amp 120V breaker in a 240v 30 amp breaker panel?

Look to see if the 30 amp panel is fed with a two wire or a three wire. If it is a two wire then you are out of luck. If the panel is fed with a three wire then the panel should have the neutral terminated in the panel. It is this neutral that you need for 120 volt connections. You didn't state how many panel slots there are in the panel. If you are able install a 15 amp breaker into the panel and connect the wires going to the load. The black wire will go to the breaker and the white wire will go to the neutral bar in the panel.
