Not in my experience. The recommended pressure tries to maximize performance, economy, and comfort. If one of these is more important to you than the others, then changing tire pressures can be an improvement. All the cars I've driven a lot have had stock pressures that I felt were a little too low. Increasing the pressure improved the perceived handling qualities, but reduced comfort. (I realize that's going in the opposite direction to what's being asked here).
Warwagon, sidewall flex will be reduced with higher pressure, but if the tires are bouncing off the ground all the time, I wouldn't say handling is improved. The sidewall doesn't even get a chance to try and flex. Even race cars have an optimum pressure that isn't just the highest safe one.
