Boot the Linux CD and see if it can run from CD. Now look for an install to USB option. If it's not there, it may not be a feature.
As to the HD to USB, that is something I have yet to see folk do today. HOWEVER I have seen folk turn that into a virtual machine IMAGE. Here's a link on how -> http://www.petri.co.il/virtual_convert_physical_machines_to_virtual_machines_with_vmware_converter.htm
