It's (sort of) possible, yes, but...

Are you talking multiple monitors, or multiple (virtual) desktops, all on 
the same( set of)? monitors?  Because you mention four desktops, but I'm 
wondering if you don't mean multiple monitors, instead.  Either way, it's 
possible, but the multiple monitors thing I think would be a more common 
request.  Multiple desktops... not so much.

Never-the-less...

One way to do it, regardless of which one you meant above, would be to 
take an image editing program and split the big image into fourths, saving 
each under a new name (so the original image isn't destroyed and to keep 
them separate), and loading them into the activity corresponding to each 
desktop (this assumes you have that option enabled, I don't) as you 
normally would, in the appropriate order.  Thus the "(sort of)" above, 
because it's not then really a single image any more, but four images, as 
four separate activities would normally take, that in this case happen to 
be related, as they're all parts of the same larger image.

If you're talking multiple monitors, it /may/ also be possible to setup a 
single activity covering all monitors, depending on whether the xinerama 
support was compiled in when kde was built, and on kde's multiple monitor 
support settings.  However, I've never actually tried building kde without 
xinerama support here so I'm unsure of how it behaves then.  I /expect/ 
that it'd configure multiple monitors as a single big display, disabling 
all the multi-monitor support for window placement, maximizing, etc, but 
it's also possible it would limit itself to a single monitor.  And if 
there's an option to spread an activity over multiple monitors without 
disabling xinerama support at build-time, thus disabling all the other 
multi-monitor support features (window placement, maximizing to a single 
monitor, etc), I've not been able to find it.   Plasma activity multi-
monitor support would seem to be behind the kwin curve, in that regard.
