nah i doubt it, those things played and ajusted some before they leave the factory. alittle playing around won't do any 'harm' except maybe to your ears if the tuning is all over the place. if anything you might help things along a bit by helping the strings start to settle in some then tune it, usually i think it's probably a good idea to let the piano 'adjust' to its new home for several weeks (think 4-8 weeks) and get some play time in then tune it, this will proably lead to a pretty stable first tuning that should last well into the next scheduled one
