Can I remove this permanently? I don't know what you call it but I know it has something to do with a mileage counter. FYI, I am emissions exempt in my state.

That the counter for the 02. No harm if removed.

If you ever plan on selling the car you may want to leave it. That way if the next owner is in a smog state he can get it registered. When I bought mine the OXS light didn't work and the smog guy failed it.... luckily I remembered the counter location and was able to plug it in. I found out why it was unplugged as it made a god awful grinding noise.

What does it "count" exactly? O2 sensors don't have any moving parts??!

It counts miles and at 60,000 turns on the light. Button resets it : edit and at 30,000 according to Ken

It counts speedometer pulses. Every 30K miles (48K km), it turns on the [OXS] light, until the reset button on the counter is pushed.
