No, this doesn't work for AMD.
The container file includes a header section with information how to
map CPU F/M/S to microcode revisions provided with a container
file. Concatenating several container files will not create an
all-embracing header section.
More details were available on the amd64.org web pages. But it seems
that the web site is not available anymore ...
