No. Not om the same way LCD screens works.
The current eink touch-screens use laser technology. The position of your finger on the screen will stop or block those laser beams and that's how the device can know your position.
Because eink does not have same supports layers (and order) than LCD, they can't rely on same detection technology.
There are tons of resources explaining the concept, it is quite interesting, but you can find some good info here:
