Skill line icons aren't used for their respective skill lines, as you can see from the Destruction staff skill line being represented with the "one hand and shield" icon.
If "one hand plus rune" was planned as a skill line at one time, I don't think an icon that's used elsewhere is any evidence of its addition being imminent.
