NO

Problem:
 f(x,y) -> f(x,x)
 f(s(x),y) -> f(y,x)

Proof:
 Containment Processor: loop length: 1
                        terms:
                         f(x,y)
                        context: []
                        substitution:
                         x -> x
                         y -> x
