Not really, the FTP server only ever responds to commands from clients,
it has no concept of running commands on it's own.  

In theory, if the client keeps a control connection open and sends a
'please wait' command, the server could pause for an event and send a
custom response to the client to allow the client to start a download.
But this would need custom commands in client and server. 

Assuming this is some private application, the easier solution is for the
client PC to have a small custom server running, even UDP which is very
easy, and for the main server to use a simple protocol to sends commands
to the client, which then triggers the FTP download. 
I did this a few years ago to get 500 remote PCs to download new files on
