The 10 minute rule is applied whether or not you are checked in, and whether or not you flew a previous leg.
The one and only time I flew hidden city, I went to the connecting gate and let the agent know I was not continuing on, and she thanked me, but didn't bother to take my name or make any notes as far as I could tell. As always, YMMV.
