Focal length of guidescope

Often short focal length guidescopes come with a warning that they're only suitable to guide main scopes up to certain focal lengths, because longer FL scopes require more precision in their guiding.

Is this something one could rectify by chucking a barlow into the guidescope if you needed a higher precision guide?
