I wouldn't recommend it. There is no reason to have two different antiviruses running on the same machine, especially a server. Both clients will be fighting with one another for resources as well as both scanning the same file when accessed. You will see high CPU usage, resources being drained, and possibly corruption.
Also, if both find a virus, both will try to lock the file and not allow access to it further. This will only bring your system to a crawl and possible crash.
If you feel the need to have additional protection on the client, I would download the free version of Malwarebytes or Hitman Pro. Both are simply second opinion malware scanners and will not consume any resources if not in use. If you suspect a virus, which your current AV is not catching, you can then run either one of these for a second opinion.
