The Hardware Maintenance Manual for the T20 says "maybe". There appears to be two different motherboards separated by 650/700Mhz CPUs (FRU 12P3360; all model types except 2647-5xx, 9xx and Lxx) and 750Mhz CPU (FRU 12P3363; only model types 2647-5xx, 9xx and Lxx). Don't have anymore info about this as I've never had a T20.
