Maybe for ceremonial or dueling purposes but not likely on the battlefield. Both Vikings and Saxons (and most other Dark Age armies) fought in close formations called shieldwalls, a weapon that needs to be swung in wide arcs is highly impractical in such a situation.
I was led to believe that people armed this way would fight in their own units instead of shieldwalls. Hmmm...have to look this up...
From wiki, about the Battle of Hastings:
"The English army consisted entirely of infantry. It is possible that some of the higher class members of the army rode to battle, but when battle was joined they dismounted to fight on foot.[l] The core of the army was made up of housecarls, full-time professional soldiers. Their armour consisted of a conical helmet, a mail hauberk, and a shield, which might be either kite-shaped or round.[72]
Most housecarls fought with the two-handed Danish battleaxe, but they could also carry a sword.[73] The rest of the army was made up of levies from the fyrd, also infantry but more lightly armoured and not professionals. Most of the infantry would have formed part of the shield wall, in which all the men in the front ranks locked their shields together. Behind them would have been axemen and men with javelins as well as archers."
