I actually used to run a Linux laptop + Win laptop setup with a kvm switch a couple years back. It worked just fine, but I found myself barely even using my Windows machine for anything but gaming. Eventually I found out my games ran perfectly on Linux, and ended up switching to linux on the second laptop as well, as navigating the windows desktop had become painfully clunky, lol
tl;dr: a kvm setup is great but be careful what you wish for. Once you start running Linux there is no going back...
It's a logarithmic scale
You can easily interact with the MS ecosystem by using the office 365 webapps. I personally prefer using onlyoffice as it's got very good compatibility with ms formats. Teams even has a functional Linux-native client. Don't forget to install the ms corefonts though!
I seem to remember there was a way to mount your OneDrive folders to your local linux filesystem but I don't use that service.
Damn that's a Jojo reference if I've ever seen one
