Hi,
Yes, you can. You can do the move first, after everything is moved to your main site, you can "revoke" license on the testing site via Dashboard > Soledad > Theme License > click on "Revoke License" or simple deactivate & remove the theme on the testing site before activating the theme on the main site.
Also, in the moving process, if you can't move the customizer data, you can use the plugin Customizer Export/Import to export the customizer data from the testing site and import it to the main site.
Best Regards,
