From the info provided: Yes you can

But if the heating element of the washing machine is running at the same time as the tumble drier, you may trip the RCD. It will be preferable to use them sequentially not concurrently. Although the MCB will protect the cable, it is much better to design a circuit that will handle the design current.

It would be useful to look at the specs of both machines to see what their actual design currrent is. Lots of European machines run at 10A not 13A.
 
its tolerable (2.5mm T&E can carry a bit more than 20A and the mcb won't trip quickly at that level of overload).

but if installing from scratch i certainly wouldn't do it that way.
