Not as far as I am aware of.  However, you can "untangle" source files
back into the org file so you could do a diff on the org file with a
previous version (especially easy if using version control).

See info manual: (org) Extracting Source Code
Take particular note of the :comments argument for the src blocks.

Caveat: untangling has sometimes mangled my original org file.  See
version control above!

HTH.
