method $obj $arg;is not an error.

You are right. It isn't. I don't know what I was thinking.

Before going on, I should clarify my point. Once a method is called, there is no way to determine the syntax used to invoke it. Your addition of a Derived class does nothing to show otherwise.

That said, I made a couple of poor assumptions. One was that "Classname" in the original wasn't really meant to be a quoted string but a bareword. I also assumed that method would be the appropriate name for the method regardless of context. There really was no good reason to assume either and I should have requested clarification.

# Actual original post        # What I assumed the OP meant
"Classname"->method( $arg);   # Class->method($arg);
method "Classname" $arg;      # method Class $arg;  
method( "Classname", $arg);   # Class::method(Class, $arg);

Mistakes, assumptions, and mistaken assumptions aside, if I understand the original post, the answer is still "No."
