Well you would have the advantage of privacy/security as your host system in Linux so would send far less telemetry data if any at all. Also no more windows updates being shoved at you or restarting your computer in the middle of work. I’m sure you’d also learn a lot to. Its always good to have options.
There it probably a very hacky way of doing it through a compatibility layer like wine but I doubt it would be either easy or stable. Have you thought about using windows as a VM within Linux and using it that way? Otherwise unfortunately then it wouldn’t be a fit for you.
Linux distributions in my experience have supported all hardware I’ve used with it. NVIDIA graphics cards sometimes don’t play nice due to drivers but in general your laptop should be supported. In regards to which distribution generally Ubuntu would be a good choice, I’ve also heard that Zorin OS is pretty good when moving over from windows and should feel a bit more familiar. Linux Mint could also be a good pick. In general most of the major distributions will work out fine.
In regards to Office I think you might be out of luck. Would the web version be sufficient for you? I personally have moved from MS office to ONLYOFFICE full time. Its quite similar and might not have all the features but its sufficient for me. There are other options like LibreOffice as well.
As you say if you’ve installed many other systems before this should be quite easy. You just need to download your chosen distributions iso and create a bootable USB in a program such and Rufus or balenaEtcher and just follow the installation process once you boot in.
Yeah if Office is that necessary there is only so much you can do to isolate yourself from windows without getting overly technical. The VM is only connected to the internet if you have it on and the network connection enabled in your VM software’s settings.
