While this works:

{\renewcommand\newpage{}\chapter{chaptername}}

(Thanks to Piet van Oostrum in this thread: suppress page break before
bib in book.)

Is there anyway to do this with \renewcommand\chapter ?

Thanks.

Well, you always sort of hate to answer your own questions.

While {\renewcommand\newpage{}\chapter{chaptername}} is a very cool
hack, and I will use it again, I found a different way.

The \chapter command is defined like this in report.cls

\newcommand\chapter{\if@openright\cleardoublepage\else\clearpage\fi
\thispagestyle{plain}%
\global\@topnum\z@
\@afterindentfalse
\secdef\@chapter\@schapter}

This statement adds the new page or pages before the chapter:
\if@openright\cleardoublepage\else\clearpage\fi

In the preamble of my doc I renewed the command and removed the
statement:

\makeatletter %keeps latex from stumbling over @ signs
\newcommand\chapter{\thispagestyle{plain}%
\global\@topnum\z@
\@afterindentfalse
\secdef\@chapter\@schapter}
\makeatother % resets @ signs to their normal usage in latex.

Works fine and does what I need.

So why do I need this? Okay. I am using twocolumns. Everytime I switch
the number of columns—that is use \onecolumn or \twocolumn—latex adds
a page break. When I switch \onecolumn before \chapter, both add a
page break. I figure \chapter is easier to fix than \onecolumn.

I would sure appreciate a prettier way to do this, but for now, it
works.

Oh, I cannot use the multicol package for this job because of its
limited support of floats.

If you are switching between two and one-column by hand, then
try without the [twocolumn] option. Then \chapter doesn't think it
needs to say \twocolumn[...] for the chapter title.

I can't reproduce this, I don't get unwanted page breaks:

\documentclass{report}
\usepackage{lipsum}

\begin{document}
\chapter{a}
\lipsum
\twocolumn
\chapter{b}
\lipsum
\onecolumn
\chapter{c}
\lipsum
\end{document}
