Well I'm pretty sure the Arm v7 is the same chip in my Galaxy S3 & Odroid U2 along with a ton of other stuff that uses Samsung Exynos processors. On my Odroid U2, I keep an XBMC/Retroarch Debian image on the EMMC with Kali and other images on SD cards. So it's definitely possible as far as the hardware's concerned.

I never tried dual booting with Kali on my phone cuz i just chroot into the image. I know it's possible tho. Do a search on the XDA forums for Kali Pwn or Pwn Pad. Some1 made an image based off the actual Pwnie Express PWN Pad image that seems to be pretty popular. I know i've seen people mention about being able to dual boot with it as the secondary rom.

Also Bugtroid's definitely worth checking out for when your on your Android image.
