You can run Romex in conduit but you have to size appropriately. Your cord is 10ga/3wire so you need to size for that. You could always just bury the cord if that's easier. It has a rubberized coating on it that is fine for that purpose.

Pulling it 500' through conduits would be an absolute bitch but sure you could spend the time and $ doing that.

There's nothing in the code as far as I know stating you CAN'T run Romex or SO in conduit, it's just probably that people assume. "well it fits in this one so it's all good" but you need the airspace for heat if it warms up while being used.

Read some more and found it in the NEC that your not supposed to bury it because it's not rated for abrasion/puncture resistance. And for some reason it's not allowed in conduit except in certain circumstances but it didn't clarify where I was reading.

However, it's your property, your land, your risk. I would personally bury it as long as it's not in an area it'll be damaged. I'd possible you could rent a small trencher and bury it inside an oversized conduit (so it pulls through easily).
