No, not what I had in mind.
In IELM you can type C-c C-b and select a buffer, and then when you eval
further sexps in *ielm*, it will be as if you used M-: with that other
buffer selected. Useful for debugging a major or minor mode.
In Eshell the closest thing you can do is wrap your sexps in a
(with-current-buffer) form, or use (progn (set-buffer ...) ...), which
is less convenient.
