No, the citizens of Vietnam are limited to 24 hour visa free transit. When the transit time exceeds 24 hours, they have to obtain a Chinese transit (G) visa in advance. This is the easiest visa to obtain in advance and I encourage you to do that on time in order not to miss your flights.
UK citizen can rely on 144 hour visa free transit, so you will not encounter any additional formality because you will be covered with this scheme. You should just be aware that the first thing upon landing in Guangzhou should be a visit the 24/144 hour visa free transit to obtain a temporary entry permit.
I'm sorry for bringing you this annoying news as far as your wife is concerned.
