I don't think you can. It's not a shell limit. It's a limit to the 
number of arguments the command itself will take. As said, the shell 
expands '*' to a list of files as the argument, and rm is limited to the 
number of arguments it will parse.

There's not really much difference in this factor for shell types; as 
for changes you'd have to hack the command's (say rm) code.

As mentioned, I'd use the find -delete combination.
