tabularx is redefining \arraybackslash (and it even tells in the docu that this is a hack:
\arraybackslash \\ hack.
\def\arraybackslash{\let\\\@arraycr}
tabu doesn't like this definition. It expect \arraybackslash to have the meaning from array.sty. So now \\ gives errors. You can give \arraybackslash locally the standard definition back:
\begingroup
\def\arraybackslash{\let\\\tabularnewline}
\begin{longtabu}
....
\end{longtabu}

The nested tabularx should be surrounded by { and }
\documentclass[10pt,notitlepage]{article}%
\usepackage{tabularx}
\usepackage{hyperref}
\usepackage{array}
\newcolumntype{Y}{>{\centering\arraybackslash}X}
\begin{document}
\begin{tabularx}{\textwidth}{@{}Y@{}}\hline
{\begin{tabularx}{\textwidth}{@{}|Y|Y|Y|@{}}\hline
\href{foo/index.htm}{A}
\begin{enumerate}
\item item 1
\item item 2
\end{enumerate}&
\href{foo/index.htm}{B}&
\href{foo/index.htm}{C}\\\hline
\end{tabularx}}
\end{tabularx}
\end{document}
This is per the documentation. I found it by doing a search on nest in the documentation.
You should probably make a couple changes though. Using \textwidth within the inner tabularx is most likely going to result in columns being too wide. Instead use \linewidth. Here is a modified nested tabularx construction:
\documentclass[10pt,notitlepage]{article}%
\usepackage[margin=0.5in]{geometry}
\usepackage{tabularx}
\usepackage{hyperref}
\usepackage{array}
\newcolumntype{Y}{>{\centering\arraybackslash}X}
\usepackage{lipsum}
\setlength{\parindent}{0pt}
\begin{document}
\begin{tabularx}{\textwidth}{@{}lY@{}}\hline
Hello &
{\begin{tabularx}{\linewidth}{@{}|Y|Y|Y|@{}}\hline
\href{foo/index.htm}{A}
\begin{enumerate}
\item item 1 \lipsum[1]
\item item 2
\end{enumerate}
&
\href{foo/index.htm}{B}
\lipsum[2]
&
\href{foo/index.htm}{C}
3:\lipsum[3] \\\hline
\end{tabularx}}
\end{tabularx}
\end{document}

tabularxwould give you nothing for images. What it does is try setting the text of each column to different widths so the line breaking changes to make the columns suitable width so that the table as a whole has a specified target width.
