If she is ‘elderly’ you can
It’s a bit of a game but there exclusions for the elderly and accompaniment of them. Her lack of English would not qualify. There are millions of people daily traveling in foreign lands and lack of local language is rarely met with empathy.
The elderly, however, can require assistance in these situations. You can tell her too look around and act confused. If she is elderly enough, this could very well pass muster.
Some disingenuous behavior may be required though.
