If you have a dock with a SCSI port, and a PowerBook "SCSI disk adaptor", and a USB-to-SCSI adaptor, then yes.
Just follow the directions on the LEM link, "SCSI Disk Mode" section, only add a new item between 2. and 3. reading "Connect SCSI disk adaptor to USB-to-SCSI adaptor, and plug USB adaptor into USB-equipped computer."
Obviously, since the Duo's hard drive will be in HFS format, you need to be using a Mac, or have HFS drivers installed on your Windows system.
