Yes, it can. In pure water you'll always have a few H₃O⁺ and OH^- ions, so if you expose the water to a direct current, you'll get Hydrogen and Oxygen gas.

If you've got chloride gas bubbling at the anode, you're not really electrolysing water the water, but you may get hydrogen gas depending on what positive ions you've got in the solution.
