No, it's a deliberate feature.  From the Emacs manual:

     If Emacs was invoked with the `-q' or `--no-init-file' options
  (*note Initial Options::), it will not let you save your customizations
  in your initialization file.  This is because saving customizations
  from such a session would wipe out all the other customizations you
  might have on your initialization file.
