No, they're using a proprietary BIOS and firmware for the embedded controller. The hardware is all Intel and of course it has a management engine[1], even all the nasty vPro "features".

From the software freedom point of view it's very much a no go, although they are apparently going to release the firmware sources and looking into coreboot[2].
