Technically, yes. I run a 30 amp RV extension to my laundry room and unplug the washer, but it is a 20 amp circuit.
Two things here. First, not overloading the house circuit and second, providing enough voltage to the AC.
I've forgotten most of the terminology and calculations from my high school electronics class, but here it goes...
I tried to use a standard household extension cord and the reading on my RV power meter dropped to 107 volts, which is damaging to the AC unit. My local dealer said anything below 108v can cause a "brownout", causing permanent damage the AC.
When I upgraded to a actual 30 amp rated extension, it popped back up to 110v.
Has to do with the length and resistance in the line. Again, stuff I forgot about long time ago
