You can't remove the lens from that camera, but if it will take screw on filters (anadded accessory is sometimes needed for this with point & shoot models) you can add lenses to the front of the existing lens.
Positive diopters (often called close up filters) will make the camera focus closer giving a similar effect to extension tubes.
Wide angle & telephoto converters are also available to screw into filter threads (some of these are dire!)
