A package manager understands dependencies between packages. You've
cherry-picked one package and not handled its dependencies.

The executable isn't self-contained. It can refer to other object files
of code.
$ ldd /bin/true
linux-vdso.so.1 (0x00007ffd13f35000)
libc.so.6 => /usr/lib/libc.so.6 (0x00007f00b6b92000)
/lib64/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2
(0x00007f00b6d91000)

The executable you're running wants, amongst other things, a
libncursesw.so.5 which isn't found. You probably have a later version
installed. ‘locate libncursesw.so’ would find it.
But installing an old version of libncursesw might just show up other
old dependencies it needs. And so on. And the mysql executable might
need other old things apart from libncursesw. You could spend days
trying to sort it.
> Clearly there is an incompatibility here with the kernel.
No, with the shared libraries you have available. But they, in turn,
may eventually be incompatible with the kernel if you have to go back
far enough.

That would seem simplest.
Or Hamish mentioned recently on this list some Python MySQL client which
he uses.
