No, because Kb7! gives the fastest mate. Every variant ends in 44. (6.) c7-c8#.
Many engines prefer c4 at first, which ends in mate too - but later, so it's
clearly second best only.

Btw. an idea in the position is, to build a *cage* around the black king by Kb7.
Watch the squares controlled by White. After seeing that cage, a human would
only have to check the pawn race.

Engines obviously have problems due to forward pruning, because at a fist
glance, Kb7 looks no good :-)) it lets the a-pawn run towards a1...
