Slab cutting

I need to cut a 10 inch square in a concrete slab and for appearance sake I don't want to cut past the corners with the circular saw. Is it possible to finish the cuts at the corners with a sawzall? (The slab is 4 inches thick).

Thanks for the suggestuions. This is an outside driveway slab on the side of the house. I’m sinking posts for an outdoor shower enclosure at a beach house. I’ve also thought about renting a 10” core drill.
