Unless you are balanced on those two wheels with no other part of the robot touching the playing surface, it's a bad idea. Any non-driven wheel or robot component that touches the carpet is robbing you of potential traction.
If a team builds a four-wheel drive robot, but with only two powered wheels, (assuming that weight is distributed evenly across all four wheels) you only have half the traction possible compared to if all four wheels were driven.
