The following change solves the issue:

\pdfstringdefDisableCommands{\let\MakeUppercase\relax}
\newcommand*{\newchapter}[1]{\chapter{#1}}

Or package zref-xr is more powerful and should be more robust then xr-hyper:

\documentclass[article]{memoir}
\usepackage{amsmath}
\usepackage{hyperref}

\usepackage{nameref}% explicit, zref-xr needs to see it
\usepackage{zref-xr}
\zxrsetup{tozreflabel=false, toltxlabel}
\zexternaldocument*{A}

\begin{document}
\chapter{\nameref{cha}}
\end{document}
