No. Lumion only allows for scaling of tile based textures.
Normally any stretching would be done in the 3D modelling application, so if the model was imported and then found later that the texture needed adjusting, it would be adjusted in the modelling app, then a quick re-export and update in Lumion to update the materials.
There other tools such as in Placing to shift the texture etc, but that is only intended really when the scaling is not 0, and the user needs to do last minute/second changes prior to render that do not affect any synchronisation with the master model in the 3D modelling app.
