Can I tie grounded/white and ground/bare from a subpanel to any grounding bar in in the main panel?
Neutral needs to go to the neutral bar.
The purpose of neutral is to be the normal path for return current which flows as part of the circuit's operation.  As such, it can only go to the neutral bar, since only that is rated to handle that current continuously and on a routine basis.
Safety ground certainly can't do that.  Think about it, that bonding screw in the main panel, is that a 4/0 AWG screw?? :) No, it's 10-32 and steel, which is a several times worse conductor than copper.  That bonding screw was never imagined to handle normal service currents.
That's why you can't land any neutrals on grounding bars and other facilities intended only for safety ground.
Safety ground is not used for anything; it only handles fault currents for the duration of a ground fault (i.e. long enough to trip the breaker).  Ergo it does not need to be rated for continuous service current.
