If that tool linked libc statically, it would have worked. Linux does provide a very stable binary ABI in form of syscalls, so long as you bundle all your dependencies. The problem is that nobody does it that way in practice, at least not with the commonly used tools.
A while ago I needed to experiment with an old file format, and I found a Linux binary of a proprietary tool from the 90s. It linked to libc version 5 (from before the Linux world adopted glibc). It would have been complicated to get it running.
I found a Windows binary of the same tool. Put it on a Win10 VM I had for other purposes. No issues.
Stable binary ABI of userland is something the Linux world doesn't do well. Win32 and COM are really good at this.
