Yes, there are several aliases for existing functions defined.

[print(f.name() + ' -> ' + str(f.aliases())) for f in 
QgsExpression.Functions() if f.aliases()]

pi -> ['$pi']
to_int -> ['toint']
to_real -> ['toreal']
to_string -> ['tostring']
to_datetime -> ['todatetime']
to_date -> ['todate']
to_time -> ['totime']
to_interval -> ['tointerval']
to_dm -> ['todm']
to_dms -> ['todms']
now -> ['$now']
$x_at -> ['xat', 'x_at']
$y_at -> ['yat', 'y_at']
x_min -> ['xmin']
x_max -> ['xmax']
y_min -> ['ymin']
y_max -> ['ymax']
geom_from_wkt -> ['geomFromWKT']
geom_from_gml -> ['geomFromGML']
intersects_bbox -> ['bbox']
convex_hull -> ['convexHull']
sym_difference -> ['symDifference']
geom_to_wkt -> ['geomToWKT']
uuid -> ['$uuid']
get_feature -> ['QgsExpressionUtils::getFeature']
