Yep,

If you insert a Name (Insert-Name-Define) into the sheet on which you have
the validated cell, and link that name to the range on the external source
containing the list, then link the validation list source to the Name you've
just defined, you can do this.

If you have a look on the Excel Help Menu for "specify the valid entries for
cells" there's a bit more in-depth info about how to do this if you've not
linked names to external sources before.
