There are some rough guidelines here:
https://www.boost.org/development/requirements.html
The menu to the right, under Requirements and Guidelines contains a few
related links.
The relevant bit to your question is this;
"Files intended to be processed by a C++ compiler as part of a translation
unit should have a three-letter filename extension ending in "pp". Other
files should not use extensions ending in "pp". This convention makes it
easy to identify all of the C++ source in Boost."
So, the .h files don't require a C++ compiler and could be used in C.
