Some Shadow derailleurs are DynaSys and no, these will not work with the OPs non-DynaSys shifters...
That is somewhat irrelevant to the topic as the OP has neither DynaSys derailleur nor shifters.
DynaSys is a Shimano marketing term to denote different cable pull ratio from all the previous 9-and-below speed systems. It has nothing to do with Shadow vs. non-Shadow or clutch.
