I don't see why not, but I can't test it out for you since I have already updated to ermine. As long as those two apks still exist in the /system/apps (I think that is the directory) then you should be able to rename them the same way and for the same benefit. Of course there could be differences between the two versions. It seems strange to me that they would ship a device with these services enabled if it can't even use them, so there is probably a chance that they aren't even enabled in the Dingo release so you might want to verify that. It could just be something that is enabled by the update for whatever reason and they never got around to disabling them, but what do I know? Somebody else that knows what they are talking about will probably respond with a more useful answer tomorrow.
