I've looked, and all I've seen are jailbroken Chromebooks and Win 10 laptops that also need to be jailbroken and are missing drivers for important things like wifi and accelerated graphics.
That is the state of non-server ARM in general on Linux.
It requires mucking with device trees and what not on most SBC's, etc.
Some of them kind of work.
The likely OEM's the SOC for a laptop like this (rockchip, amlogic, etc) are mostly non-helpful. Though rockchip is getting upstream reasonably well now (IE you could probably build a mainline kernel that works).
But honestly, I would expect a linux laptop built with any on-market ARM SOC to be a mess right now.
There is actually one SBC vendor who runs linux in a container under the android kernel because the android kernel has much better ARM hardware support :)
(which is probably right - most of the SOC's you'd put in a laptop are being built mainly for android based set top boxes, tablets, etc)
It would take a couple iterations and dedicated work to get somewhere good.
