If your image is a sparse *bundle*, then yes.  

I have a sparse bundle that is 1.27GB in size.  Inside are 87 or so 
bands (files) of 16MB each.  If I add another 10MB of data to the 
image, just one of those bands gets modified, and/or one more band gets 
created.  The rest of the bands remain intact.  So the next time Time 
Machine runs, it only needs to add the changed and/or new bands to the 
TM backup disk.  If this were a regular disk image, TM would add the 
whole 1.27GB image file over again.

You should be able to convert your regular sparse image to a sparse 
bundle with Disk Utility's Images -> Convert menu item.  Or, create a 
new empty sparse bundle, move your files to it, and delete your old 
image.
