Yes.

Well, kind of. The trailing "-" in the path specification above means: grant
that right to all files in this directory and all subdirectories thereof. So,
as a result, the name of your servlet really doesn't matter, since it resides
somewhere in (a subdirectoy of) the webapp-directory.
But better to see it just the other way round: you don't adopt your webapp to
match the configuration parameter but the configuration parameter to match
the webapp.
Example: the servlet that shall be able to execute an external binary is
contained a webapp named "My1stWebApp" which is placed at the default
location (i. e. the location tomcat's default configuration specifies). The
path to your webapp's directory will therefore be
${catalina.home}/webapps/My1stWebApp
and the configuration parameter
grant codeBase "file:${catalina.home}/webapps/My1stWebApp/-" ...
If you have for example placed your webapp in
/some/strange/dir/mywebapps/My1stWebApp
the entry in catalina.policy should the read
grant codeBase "file:/some/strange/dir/mywebapps/My1stWebApp/-" ...
