Perhaps every other OEM are running antennas through the case that have exactly the gain you'd expect on the bands you'd expect; while Lenovo are using better-than-average antenna designs together with lower signal amplification to achieve the same SNR with lower total power consumption. If that's the case, then swapping out the wi-fi card for one that hasn't been programmed for below-standard signal amplification, will get you a system that's above the FCC limits.
