You should be able to make a bluetooth connection which would allow any audio on the laptop to be routed through the muso.
I just tried it with a mac laptop (no windows available to test) and it worked. The first 20- 30 seconds seemed a bit patchy/stuttery as if it was having trouble with the signal but after that it seemed to be solid enough. It looks like it should be fine but if it were me I’d probably take the laptop into the nearest stockist and try it out to be sure.
My music all goes through the system either via uPnP using a plex media server on a NAS drive which gives me all my local music files or failing that I have a mac mini hooked up to the TV with the TV audio routed through the muso via the optical audio input which covers pretty much everything else so I’ve never tried the bluetooth connection before just now. I could connect the mac mini directly to the mu-so but routing via the telly means that it can be used as a soundbar for broadcast tv.
