Yes, this is very frequently done. Training is far more computationally expensive than evaluation in most cases. I don't know of any specific cases of this being down with a raspberry pi, but many phone apps, for example, have this sort of architecture. Train a model on a powerful server/cluster, send model to phones for use, phones collect more training data that is sent to server/cluster, repeat.
