Intel processors using the Haswell architecture are very popular in 2013/2014-era ChromeOS devices.
Support for Haswell Chromebooks has been implemented in upstream Linux with aplomb, so you should be able to run any Linux distribution you please with little to no friction.
Factory firmware support for booting legacy OSes via SeaBIOS is common, but custom firmware is also available for all Haswell models as well -- see Firmware.
