Yes, that is what they are designed for. The hydrophobic fabrics dry quickly, the flat seams do not chafe when wet, and the construction is intended to be worn under a wetsuit or alone during the swim. However, for non-wetsuit swims in warm water, a tri-suit may be more comfortable as it eliminates the potential for the jersey to ride up during the swim.
