Hi John.
It is a little hard to tell, in my experience the practical way is to get the machine and do some testing and recognize the components/chipsets that it has.
This is my personal option and it may change according to the machine configuration.
According to the article it has "Intel Core i5-4570T". So OS/2, ArcaOS or eComStation should boot with the ACPI driver, if the BIOS has an UEFI legacy mode on it.
- Intel HD Graphics 4600, should work with Panorama or SNAP
- Intel Centrino-N 105 Wi-Fi card (Mini PCIe)- I don't think it will work yet.
I'm not sure if it comes with wired ethernet and what sound chipset does it has.
If you have the exact model you get some more hardware info details on the Lenovo PSREF Book:
