Yes, Restart is not needed for schema changes apart from some configuration changes, such as the DataDir location and IndexWriter related settings in solrconfig.xml which can not be changed and made active with a simple RELOAD action.
Note :you might have to reindex the data in your collection after the reload based on what changes you make to schema.xml or solrconfig.xml Did you get any error while uploading or reloading the collection. ideally once the config upload is done , you can validate if your changes are seen in solr admin UI and then for those changes to be in action you can reload the collection.
