No, Ned wouldn't have told Howland about Jon. He would have sworn him to silence, but would not have seen fit to reveal to Howland who the baby's father was. In any case, Howland had been wounded by Ser Arthur Dayne, so he would be out of the picture for a while, during which Ned could have taken Jon with him to the North.
