It depends.

kpsewhich automatically guesses a format if none is specified. This
guess uses the filename's extension (.cnf in this case). The guessed
search path in this case (extension .cnf) is the wrong one (it is the
one for searching texmf.cnf files and this search path is a very special
one because it is the only one which does not use the paths specified
in texmf.cnf). Depending on some details of the installation, this
might work, but it can fail.
