To a degree. It requires a more directed bump/push than defending a mecanum robot, and a 6/8 wheel drive train can better resist the imparted turning motion by turning against it, allowing you to hold a stalemate. Trying to drive a mecanum robot that is already slipping is an exercise in futility. The bump also causes rotation more than sliding, which would keep general field position close to static. In this case a good catcher would be orientation-agnostic.

Having a robot that can be pushed in any way is disadvantageous to being a good target for catching, so I'd say the best pure catcher is a robot without wheels. However, making the trade-off of allowing some pushing in exchange for the ability to move and complete other tasks could be a successful strategy. Toggling between a drivetrain and a traction device would give the "best of both worlds" at the expense of complexity (independent swerve being another solution, albeit even more complex).
