But \mathbf{} works. \boldmath and \mathversion{bold} shouldn't care,
whether bold math is achieved with a bold type face or faked. It should
only work like invoking \mathbf{} at the beginning of each \(\) and \[\].
Is there a workaround or do I need to type \mathbf{} at the beginning of
each \(\) myself?
You shouldn't use \mathbf to make large part of an equation bold.
\mathbf is meant for single symbols and only for things like numbers
and characters. In unicode math it works by mapping them to other
unicode position. E.g. a \mathbf{0} is the MATHEMATICAL BOLD DIGIT
ZERO character at position U+1D7CE.
OK. I wasn't used to this when using normal latex. Of course I don't use
bold math often, but for school it sometimes happens.

If you want a bold math font you should at best use a font which has
a bold face.
Is there any good unicode-math font with a bold face (Asana Math and
XITS Math don't work)?
In other case you will have to fake it:
\documentclass{minimal}
\usepackage{fontspec}
\usepackage{unicode-math} % Interesting Line 1
\setmathfont{Asana Math}
\setmathfont[version=bold,FakeBold=3.5]{Asana Math}
\begin{document}
$\sqrt{\frac{\pi r^2}{4}}$
\mathversion{bold}
$\sqrt{\frac{\pi r^2}{4}}$
\end{document}
(It works fine with xelatex but for me not with lualatex.)
Thanks for the clarifications and the hint to fakebold.
bye
