If by "technical debt" you mean something that requires updates and maintenance, then yes, because it's a living language. Perl has the advantage of being frozen in time, but it has the disadvantages of not being a living language: younger programmers not being prepared or willing to touch it, likely less library support for newer technologies. That constitutes technical debt as well, albeit of a different kind.
