You can pass any geometry in the FeatureLayer query (FeatureLayer | API Reference | ArcGIS API for JavaScript 3.17 ).

var query = new Query();
query.outFields = [ "*" ];
query.geometry = myCostumExtentPolygonGeometry;
featureLayer.queryFeatures(query, function(featureSet) {
 // process results
});‍‍‍‍‍‍
