Is there any chance nowadays of getting Fedora ARM running on cheap Allwinner 7" Android tablets that ship with Android 5.1 ?

I am thinking of the likes of

7" Android Tablet
Android 5.1.1 operating system
Quad-core processor up to 1.2Ghz
1GB RAM
8GB Internal Flash Memory

Further digging reveals:

CPU Allwinner A23
GPU: Mali-400MP

Would booting Linux be a pain like it was discussed here about three years ago, or are there more mature solutions wrt replacing unlocking/replacing bootloader or booting from external usb flash drive?
