The strong forces operate up to range of $10^{-15}$ meters. The calculations for Muon reveal that they can be propagator for distances up to $10^{-14}$ meters. Why can't I ignore the factor of 10 and call muons the Yukawa particles for short range strong interactions?

Because muons don't carry a color charge, and hence don't participate in the strong interaction...
