For a laptop battery there are no 90W or 65W but there are 90WH and 65WH.

If the adapter has the correct voltage, connector type and polarity, there should be no problem. The 65W and the 120W is the number of watts of power the adapter can provide. If the laptop needs 65W and the adapter can supply 120W, it should work fine. Had it been the other way around, the adapter might not be able to supply enough power for the laptop and it might get too hot and burn out.
According to Lenovo, you can use a 65W AC adapter for T500 models equipped with integrated graphics chips (Intel graphics). If you have the discreet graphics chip (ATI graphics), you should use the 90W AC adapter.
