I guess the answer is yes except for whitespaces.
The namespaces are recorded in the Module.symvers file,
which is also parsed by external programs like kmod.
Using whitespaces within namespaces may confuse the field separators.
Otherwise, the namespace is a simple string matching as far as I can tell.
