Sure, but there is no free lunch and as your system gets older and
older you'll find that more and more modern software doesn't work with
it. Additionally there are increasing security risks because the
vendor is no longer releasing security patches.

That said, if you really really wanna, you can use
https://docs.conda.io/en/latest/, https://spack.io/, or similar to
install recent software releases on old systems.

Best,
