A HILL is defined as a "naturally raised area of land." Water is not land. So no.
You can, however, swim "up," just not uphill.
Hmmm...ok, I will grant that that is one definition of a hill, but not the only one. To apply the scientific rigor that has been given to such problems as "airplane on a treadmill" we should perhaps all agree on what it means to swim uphill.
