Renaming your custom file behind Emacs' back is about as advisable as
renaming your .emacs file.  The only valid reason would appear to be
to temporarily disable it.  Moreover, you get the same problem with
the `setq', unless you edit your .emacs.

Note that when you rename your custom file during an Emacs session and
then change `custom-file' using Custom, then this poses no problem
whatsoever.  Custom writes into the new custom-file all options with a
non-nil `saved-value' property.  It does _not_ read from the old custom
file.  But unless you renamed your old custom file or played games
with `saved-value' properties that you should not be playing, the
result will be equivalent with reading from the old file.

Sincerely,

Luc.
