The textcase package, loaded with  \usepackage[overload]{textcase}, seems to solve the problem without using \lowercase and works with mixed cases. Eg,

\documentclass{memoir}
\usepackage[overload]{textcase}
\usepackage[utf8]{inputenc}
\usepackage[backref,colorlinks=true,citecolor=blue,linkcolor=blue]{hyperref}
\chapterstyle{thatcher}
\begin{document}
\tableofcontents
\chapter{A chapter}
\begin{equation}
y = x^{2}
\label{Abc}
\end{equation}
\chapter{Another chapter Eq.~\ref{Abc}}
\end{document}
