I hope you have an uptodate hyperref. Then the following should work:

\documentclass{article}
% All has to be done, _after_ the .aux file with the labels
% is read and _before_ hyperref uses the value of pdfstartpage.
\AtBeginDocument{%
  \begingroup
    % initializise \StartPage with the first page
    \gdef\StartPage{1}%
    % local assignment of pageref value to counter value
    \count0=\hypergetpageref{VL6}\relax
    % if undefined, \hypergetpageref returns zero and
    % prints a warning
    \ifnum\count0>0 %
      \xdef\StartPage{\the\count0}%
    \fi
  \endgroup
  \hypersetup{pdfstartpage={\StartPage}}%
}
\usepackage{hyperref}

\begin{document}
\tableofcontents
\newpage
\section{Hello World}
\newpage
\section{Foo Bar}\label{VL6}
\newpage
bla bla
\end{document}
