I don't think so. Though "U\r\4c (" parses in the core grammar to a FUNCTION token with value "Url(", which after applying the case-insitivity rule per [1] is equivalent to "url(", there's no wording in [2] that suggests that the character sequence "url(" that starts a URI value needs to be the URI token, it could also be a FUNCTION token.
It follows that "Url(" as appearing in the testcase must be treated as an URI value as per CSS21, section 4.3.4, making the test case correct.
