I'm currently not in a position to test this myself, but I do know that similar applications (Solid Edge, for example) have been used over remote connections. I'm pretty sure we did that in Citrix at the time.
For the SE application, I'd say it's doable for "light" work. It's not optimal, though, due to latency - depending on your connection it could even be unworkable. However, for SE, localized access was required - as the CAD files in question were stored on the local server...
However, since Fusion is operated from the cloud, I fail to see the need for working through a Citrix interface? Just install Fusion on your own system & connect to the project through the cloud? It'll offer a much better efficiency...
Hope this helps?
