Using a conditional loan letter for my UK student visa application

I’m an international student attending a top-2 uni in the UK for my MBA and I’m in a bit of a crunch. My school resumes on the 11th of September and I’ve gotten my CAS and applied for a priority visa online, but I’m being delayed by Prodigy Finance’s matching process.

Is it wise to simply use the conditional loan letter for my documents submission?

PS: I have a 75% scholarship and the loan offer covers the remainder of my cost of attendance. I have all other documents ready to go.
