This code doesn't require the Game Objects to be empty, but that's fine. They just need Transform components, and you can't have a Game Object without one!

// Populate this array in the order you want the line to travel. var transforms : Transform[]; private var lineRenderer : LineRenderer;

function Awake () {
    lineRenderer = GetComponent.<LineRenderer>();

 // Use this line again later, if transforms.Length changes. 
 lineRenderer.SetVertexCount(transforms.Length);

function Update () {
    for(var i = 0; i < transforms.Length; ++i) 
        lineRenderer.SetPosition(i, transforms[i].position);
}

Keep in mind, the Line Renderer doesn't actually make lines. I recommend Vectrosity for that.
