What is needed is finding out which NFC chip(s/set) is being used in your 
device. Assuming it is supported on Linux, it could be as simple as enabling a 
kernel config option.

I'm guessing the device came initially with Windows and if you still have 
that, it could be that it can tell you which NFC hardware is being used.
Another option is asking Lenovo directly.

You could also try "modprobe nfc" and see whether dmesg (f.e.) outputs 
something which would give a clue as to the NFC hardware.
