No, you can only see a performance loss with yylineno 
(in the new code) if all these conditions hold:

  1. The rule could possibly match a newline, and
  2. The rule matches frequently or matches a lot
     of text, and 
  3. Your parser has such low overhead that a rescan
     of yytext would even be noticable.
