Well, if you immediately overwrite the hard drive of the machine with some Linux variant (as I think the GP implie), I think it will solve a lot of problems like this from any manufacturer.
No it doesn’t. If memory serves, Lenovo rootkits have been in the UEFI firmware which auto-install hooks into the OS after boot.
Linux is not magically immune to this attack. One could argue it is more susceptible than other OS due to lack of binary signature checks on executables at runtime (at least by default).
