you mean the 65 watts adapter? If your T410 came with Nvidia GPU, it is recommended that you use the 90 watt adapter, but you can still use the 65 watts adapter when the battery is full, but the laptop maybe throttle down accordingly.

It will work with the 65 watt, but may not run and charge at the same time. I've borrowed a 65 when I forgot the 90 for my T61p and it would either run fine (at least with the battery in place) or charge the battery, but pretty much not do both at once.
