You could say that. I used Docker containers to do that. You need to mount the data directories as an external bind and then you can run two versions on the same host. Another trick is something like this:

All of the databases are, technically speaking, on the same host. If you need the hosts to see each other, you will need a DNS server. I recommend dnsmasq, it's easy to setup and works flawlessly.
