With appropriate software. You might need to suppy external power to the keyboard.
You can read an interesting discussion of USB OTG (host) mode the kindles starting here:

But especially, in that thread is a link (now dead, but here is an archived copy):
USB Host on the Kindle 4
He is using a USB network card and USB sound card on his Kindle 4, but he is using a custom kernel:
Kindle kernel
But unfortunately, archive.org did not archive his kernel source code git repository. Sad how interesting parts of web history up and vanish like that...
Hopefully a keyboard driver would need minimal kernel mods, and may only need a loadable kernel module (.ko file). As I mentioned in that other thread, look at what the Nook folks did to activate USB OTG on their very similar devices...
EDIT: It seems that archive.org is a bit fussy about HOW you find and navigate an archived private git (or what remains of it), but I did find the gitweb LOG for the source code files (perhaps useful for "googling for clones"): https://web.archive.org/web/20150506....git;a=summary
