Not on the Macs. There should be an uninstall script in the LANDesk folder. Can't remember the exact location off hand. I think it's in the Application Support\LANDesk folder.
The Uninstall script for the 8.8 client can also be copied to a flash drive or other file server from the LANDesk server and then run locally on the machine in question. In 8.8 they removed the actual uninstall script from the local client. In previous versions the uninstall script is located in /Library/Application Support/LANDesk
