Tom,
You can add in a World Terrain basemap from ArcGIS Online in ArcMap. Choose Add Data > Add Data from ArcGIS Online > Browse by "terrain" > Choose the World Terrain Base by clicking "Add"
This basemap loads in via an internet connection to ArcGIS Online and shows terrain with no labels whatsoever. You can then zoom in to Europe and even clip the basemap down to that extent if desired.
