As long as its in a different corner to the HG, I reckon youll be right. My HG points into the bottom right corner as Im looking at it, and the probe is in the bottom left.
My BMs paddle spins clockwise as you look from the top, so I have the probe coming in from the side so it "points" clockwise too, so the beans werent hitting it end on, which I thought might dislodge it.
My probe sticks into the pan about 25mm Id say, and is about 10mm away from the side wall. I have 4 holes drilled through to use, lowest is about 10mm off the floor of the pan, with the other holes spaced about 10mm apart upwards from there, the theory being probe position can be varied depending on the roast batch size.
