Short Version: I am running a dual boot of W10 and CentOS 7. They each have their own separate ssds and Grub allows me to easily dual-boot to each of them easily. I have already freed up 256GB of ssd space on the W10 drive as its own partition. Can I safely install Windows 7 on that partition without breaking the bootmanager/grub and would there need to be any extra steps needed after installing it such as updating GRUB?

Thanks.

Long Version: Some of my software plugins for Maya are incompatible with Linux and my 3DConnexion Space Mouse Pro is hobbled by bad drivers and will not even work with Maya. Windows 10 is too hard/inefficient on resources such as VRAM which is one of my most important resources when it comes to texture painting and GPU rendering while just being slower overall in CPU related tasks. For this reason I want to install Windows 7 to get back the functionality of my most important 3D modeling tool and plugins while not losing out of VRAM for extremely dense 3D scenes or textures. I will keep Centos as some programs (such as Blender and Houdini) run worlds faster and more efficient while leaving Windows 10 alone in case something breaks thus I will still have an O.S. I can fall back on.
 
Your main problem will be disk partitioning. You will need separate primary partition for Win7, and a way to restore GRUB (if this is what you use). You can also try EasyBCD and use Windows boot loader to switch between OSs.

I would take your assertion "Windows 10 is too hard/inefficient on resources such as VRAM" with a (big) grain of salt.

So would I, a very large grain. If you use a PCI/PCIe GPU with it's own VRAM on board, Windows 10 is just as good as Windows 7 in that respect, your performance issues lie elsewhere.

If you're not using a PCI/PCIe GPU, well you should be for your type of computer use.

Don't know how you expect meaningful help with no system hardware specs disclosed -
