Many programs are dynamically linked to at the very least, libc. If the system libc is older than what the binary was developed for, it will often fail. Failures going the other direction are less common, but can and do still happen. If the binary was statically linked with everything it needs, you've got a pretty good chance it'll work, but that's a bit harder to do with GUI programs that need to interact with X or Wayland.
