ULMFit sentiment analysis using a different Dataset

I was trying to apply ULMFit on yelp dataset to gather sentiment. As the yelp dataset is not labeled, Is it a good idea to use transfer learning from Amazon Reviews dataset and use that model to predict sentiment on Yelp Dataset? As Amazon reviews are towards products and Yelp Reviews are towards Businesses and service, does there be any kind of transfer learning problem in reviews from different domains??
