If they've already been registered as ham, yes; but you can do this at the
same time you register them as spam.  The -N option unregisters them as
ham, the -s option registers them as spam, but these can be combined:
bogofilter -Ns

Similarly, if you have messages which have been registered incorrectly
as spam and now need to be unregistered and reregistered, use
bogofilter -Sn

In each case, combine these with other options as needed.  (For example,
if you want the X-Bogosity header added, you need appropriate options
for that.  Ditto for spam and ham cutoffs if you're setting them on
the command line.  Etc.)  This should be pretty straightforward if you're 
already registering messages.
