Yes, it's doable. I've been using Windows 10/C7 for two years on my laptop.

Windows 10 uses UEFI boot on most recent systems. Basically the BIOS is 
like a bootloader and can load EFI binaries from different OSes from the 
same UEFI partition. The idea is that you need to boot CentOS 
installation disc in UEFI mode, and remember to mount and install CentOS 
UEFI bootloader into Windows's UEFI boot partition. You can create other 
C7 partitions as usual.

This is a record of what I did to my system. Hope it can help:
