  To be a valid "distance" it is only necessary to demonstrate that the norms of matrix differences satisfy the simple axioms for a metric space.  The facts that this particular metric is complete and that we have a vector space is unneeded.

  However, Simran's use of the adjective "minimum" suggests that perhaps a somewhat different meaning was intended.
