Yes.

The only "restriction" is in being careful about how the included 
keywords mix with the keywords in the header. The resulting header 
has to make sense and be a valid header.

The .IK directive acts just as if the keywords were in the header, in 
the place where they are. If some keywords are duplicated in the 
header and the keyword file, there may be some unintended 
consequences.

If the header has a duplicated keyword, for example

Keyword=A
<other keywords>
Keyword=B

then that is interpreted as:

Keyword=A,B

So if for example, you have a header like this:

[log in to unmask],Quiet:,[log in to unmask]
.IK kwfile

and the kwfile has:
[log in to unmask]

then C will be a quiet owner along with B, and A will be a nonquiet 
owner.

However, if the header has:

.IK kwfile
[log in to unmask],Quiet:,[log in to unmask]

then C will be a non-quiet owner, and the primary owner.

If the keyword file contains a keyword that is only allowed to have 
one parameter and the header also contains that keyword, then you 
will get an error.

And so on. But as long as the resulting headers make sense, anything 
can be in the keyword file.
