Cut a big hole in concrete where it "should" be. If there, rejoice. If NOT there, refill big hole with concrete and complain about it at the next few family gatherings.

You can see the cap? I'd assume that if you can see the cap then there would be plumbing there but I also think that running a snake would be a great idea. My house has a spot in a spare bathroom that is suspose to be pre-plumbed for a bath tub but it would be under concrete.
You can call 99 dollar rotor rooter and they can send a camera down the line for 99 dollars.... or you can pull the clean out cap and send a snake down from a drain and watch for it at the tie in through the clean out.
