10 gallon is easy to move. Do it.
I moved all my tanks when we de-did our hardwood floors. That was a lot of work. (The floors and the tanks).
Then I was very careful to keep the windows open in the rooms with the tanks, and where we were working on the floors. Towel stuffed under the door to the fish so the fumes did not get into those rooms.
I am not sure you have to get that paranoid about paint, though.
I would sure add fresh activated carbon to the filter, and change it every few days while you are painting, and for perhaps a week after, even if you cannot smell anything. AC adsorbs a lot of different things.
The tarp is a good idea, and if you can put an air pump outside a window you would be adding more pressure to the space under it, so less room air (with paint fumes) would get near the tank.
