The blade is round. Unless you can plunge to the diameter of the blade you'll get a pocket with an arc ramp at either end you'll have to cut anyway. The other suggestions like a scroll saw are just as good and I bet you will end up there anyway. No sense in adding risk by increasing the surface area between the blade and work and that circular saw is likely to screach.
