No, it's not. All you have to do is follow the logic. If it were an adder, S1 would have to be affected by inputs on A2/B2, and it quite clearly is not.
I don't know what that is but it sure as hell isn't an adder.
Run through the states (plug in 0000 through 1111 on the A1/2 B1/2 inputs) and you'll see what I mean.
