The validator will also be fine if you do not escape the ampersand in
this case, because the &lang is interpreted as entity reference and
thus as a left-pointing angle bracket instead of an ampersand followed
by "lang". If you escape the ampersand in the HTML representation of
that URI, this won't happen.

The validator will only complain if there is "no such entity".

No, I explained this in [1] in detail. You only have to escape the '/'
if the '/' has a special meaning for <http://www.example.org/check> and
you only have to do it in order to ensure correct interpretation of the
URI, not in order to make it syntactically valid.
