Can't reply to the other posts, as I assume they were deleted. I dug a bit further, and I found that it is a Synaptics sensor, which was unsupported on some ThinkPads according to this. However, yours might work, but you can't know for sure without checking the actual product. A fingerprint sensor is nice to have to be honest, but you can definitely use the laptop with Linux without it.
See if anyone else has the same version of laptop, or try asking Lenovo support for more information. You would need a USB ID like this: 06cb:015f. I wish you good luck!
