Technically yes...but not by much.
You have a fixed combustion chamber volume and take the gasket volume as constant. If you increase the swept area of the cylinder then technically you increase the comp ratio. However piston manufacturers know this so they increase the dish size on most pistons to compensate for this on standard engines.
So if your going bigger just to increase comp it probably won't happen. Better to select a better piston for the job with a different crown setup to increase it.
