Well, it comes down to a difference in processor architecture. There is a big difference between ARM and x86/64 processors. ARM is mostly used in mobile devices like phones/tablets and x86/64 is typically laptops/desktops. If a game (or program) is going to be released on a certain platform, then it needs to be specifically created using that platform's architecture. That's why your laptop doesn't run Android/iOS apps and why Windows/Mac programs and games don't work for Android/iOS. A developer has to make their game for that specific computing architecture. Think of it like trying to insert a bluray into a dvd player, sure they are both movie formats, but the format themselves are targeted for a specific device (in this case dvd players vs bluray players).

Emulation is quite robust on Android via multiple emulators for various consoles. However, what you're asking is full virtualization of an operating system (Windows 10 or higher in this case) which just isn't viable on an Android tablet due to it being an ARM processor device, and many tablets being relatively low-spec. You need a fair amount of horsepower to run an OS on a VM at a decent speed. Even on a desktop computer or laptop playing games ends up being slower due to not accessing the video card directly (I believe, don't quote me, but it is slower generally especially for more graphic intensive games). Here is a thread on Reddit where someone asked the same question which provides some more thorough answers than what I just wrote: https://red.ngn.tf/r/virtualization/comments/l84esp/how_to_run_windows_10_on_a_virtual_machine_on/. Your best bet in this case is using some type of game streaming service that has an Android client and Disco Elysium on their catalog, otherwise there isn't a chance that you'll be able to accomplish this.
