You mean a named function (a lambda is a function). Yes, you can do
that. I suggest to have a look how some Emacs package do that,
e.g. package.el (look at `package-menu--print-info-simple' and the
action function `package-menu-describe-package'. Seems the action
function should accept a button as argument.

Seems you can either put a property on the button and refer to the
property value in the action function via `button-get', or just use
`tabulated-list-get-id' to get the ID.
HTH,
Michael.
