Using a custom field is probably the most straightforward way to create a smart group for this, unless the SCCM client shows up in the Programs and Features control panel. For the latter you could create a smart group based on installed software inventory. I'm assuming that you're targeting Windows clients rather than Macs but wanted to verify but let us know if that's actually the case.
Actually the better way to do this if you were targeting clients for removal of the SCCM client would be to use a fileset requirements script to run your SCCM client uninstaller fileset. To do that we'd need to know how you normally identify that the SCCM client is present (by the presence of a particular process, file/folder, or registry value?).
