Why? What are you trying to solve? Or, rather, what are you trying to break?

In short - no. You stop the application [1].

Stop the holder of that dataset and upon cleanup the dataset will be released 
by the system.

Use D GRS command or ENQ in ISRDDN to see who is holding your dataset and how. 
Then you stop these ENQ holders.

As others said about FREE=CLOSE, in REXX you do a ALLOC, do stuff, then a FREE.

As others said, perhaps (?) with an APF-ed program standing outside the ENQ 
holder address space, you can do 'tricks' at your own career ending peril and 
serious data loss.

[1] - Or you give a command (if so programmed in the first place of course, say 
in a menu item or inside the program logic) to do a FREE.
