If you mean 'yoke mount' for a GPS for example, then success will depend on the weight of the GPS : I had no problem with a GPS 90 but the Garmin 295 was far too heavy and vibrated so I couldn't read it unless I held yoke with 2 hands (after dynamic balancing of prop for you smart *rses).
If you just mean a clip for charts then unless your charts weigh 800gm I don't see a problem.
Which begs the question why don't you stick your charts on your knee like everybody else does?

PS I've often wondered what the affect of a yoke mounted GPS would be on a pilots chest in the case of sudden deceleration as in a crash (hate that word) landing.
I can still vividly remember a trip to AAIB Farnborough when the cockpit dials of the Korean Airlines Transport which crashed at Stansted a few years still had bits of pilot in them.
