Not easily.  Emacs uses Posix errno variable values to produce the
text of the error messages.  Windows has a much richer set of possible
error values (this one is ERROR_SHARING_VIOLATION), but the Windows
runtime and sometimes Emacs code itself map them to the Posix errno
values, in this case EPERM, and only those errno values are exposed to
the Emacs primitives.
