I don't know about PADI Europe but I do know that my Instructor (PADI USA) said that our checkout dives had to be at least 20min to count. He didn't specify any minimum depth just the time.
I take that to mean they count as dives. I also believe this is only a requirement so that you spend enough time in the water for the instructor to evaluate you. I say this because depending on the gas your breathing and depth that you go to there can be post-training dives that will not allow you to stay under that long.
I would say OW dives of any type count, confined water (pools, tanks and aquariums) dives don't.
