No, a foreign patent agent with limited recognition cannot represent applicants in all USPTO matters. The MPEP clearly states that A foreign patent agent granted limited recognition may not represent applicants or parties in trademark matters, ex parte or inter partes appeals to the Patent Trial and Appeal Board, petitions to the Director of the USPTO, disciplinary proceedings, or in any other matter before the Office. (MPEP 402.01) Their representation is strictly limited to the presentation and prosecution of patent applications before the USPTO.
