Yes, the CH keyboard has a different layout to that shown in picture 10, with an L-shaped Enter key and an additional key at the bottom left of the Y key.
The Yoga I received has a keyboard with the order "QWERTZ", the "@" is on the "2" key, "ü"/"!" between "P" and "Enter", and "ö"/"ä"/"£ä" between "L" and "Enter". However, I cannot say whether this corresponds to the ISO classification.
