I can only say that I have always used a dedicated /boot partition for a 
Linux distro, I have never had a Linux distro have access to a /boot 
partition in a different Linux distro, and the only thing I have ever 
manually done with a /boot partition is back it up somewhere offline. 
What problems this straighforward use of the /boot partition, and 
installing the bootloader on it, can entail in this sort of scenario, 
which must be pretty common, I cannot guess. I do understand that 
CentOS7, as an Enterprise Linux distro, may want to limit an 
installation of grub2 from being installed on a separate /boot partition 
but at the same time the assumption being made is that CenTOS7 should 
now controlling bootup of a computer. I think thsi needs to be documented.

I did manage to install grub2 in my CentOS7 /boot partition, and 
everything seems to be alright. The only negative effect is that CentOS7 
changed my BIOS time incorrectly. But that has been fixed.
