I'm not particularly familiar with Ubunto, so I cannot
list in detail all the specifics necessary to accomplish
this.  But it is actually fairly easy.

You simply need to have two separate root filesystems on
your external hard disk.  I've done that using Slackware
and Lilo.  I think Ubuntu uses Grub, but it certainly
will be able to do the same thing.

If you separate the various filesystem onto different
partitions, you can have the same /boot, /usr, /var, and
/home partitions for the laptop and the desktop system.
I'd use maybe a 1GB /root for the laptop and another for
the desktop.  Then a /usr partition large enough to hold
whatever that distribution has that you want to install.

I'm not sure if there would be variations in /var
between two different systems like that.  There might
be!  So just to avoid that as a problem you might have a
different partition to mount as /var for each system
too.

The /boot and /home partitions can be the same.
