Yep! I can compile a program on Windows and expect it to work on any Windows OS from the past ~15 years that has the same CPU architecture. Linux? Each binary is more provincial. I want to try some of the tricks like MUSL though; haven't explored the space beyond default compiler options.

Ironically, you can run almost any vintage Windows or DOS software on any modern GNU/Linux OS too, using compatibility layers.
