Whilst your uploads will work – the moment you push new code, or your application is restarted you will loose any uploads.
Heroku uses an Ephemeral file system, in that each dyno receives a separate copy (slug) of the originally deployed code so uploads would only exist on the dyno that handled the upload (https://devcenter.heroku.com/articles/dynos#ephemeral-filesystem).
You need to use an external persistant data store like Amazon S3, Rackspace Files etc – fortunately with Carrierwave it’s trivial to update it to use it as it supports it out of the box.
