Absolutely! And from my experience, although this may be less true if you're taking a chance on the 3.2.3 beta, the exports from vanilla Godot are almost guaranteed to work on the other desktop systems as long as the person downloads the right byte size install (32- or 64-bit). The only point where there's really issues is if you add some kind of module or feature outside of the core Godot Engine, in which case the export success is really all up to that specific module.

Also idk about Mac (I have the feeling it's the same because it's also Unix based), but Linux has very strict capitalization for files. So like I've collabed with Windows devs before where they have a folder called "Scenes" but in the code they're loading "res://scenes" which works for them but it breaks on Linux. I'm not sure if the export process fixes this, but if you ever have like... external files for your game outside of the .pck then it would be good to doublecheck your capitalization.
