When I used the Avahi Zeroconf Browser tool on my Lubuntu 16.04 machine, it lists only one of the machines on the LAN as a "Workstation".
What's the criteria for listing a LAN computer as a "Workstation" in this tool?

You're seeing a _workstation._tcp service being published by that host. (It doesn't have any other purpose except for making the computer show up in a list.) There is no special criteria; all entries correspond to some or other service published via DNS-SD.
This (and a HINFO record with similar purpose) can be enabled in avahi-daemon.conf, and used to be published by default but was recently disabled for privacy reasons.
