Not directly - but there may be other ways to achieve your objectives.
One way is by using categories. The ease of this may depend upon how you are executing tests on your build server, but if you attribute all tests that should run on the build server with a specific attribute (i.e. [Category("BuildServer")]), you can then selectively run only these tests on the build server without needing to ignore them.
Another option is to use
conditional compilation to switch off the Ignore attributes for the NCrunch test environment. For example:
#if !NCRUNCH
[Ignore]
#endif
.. You may find this more useful if you are trying to exclude a small minority of tests, as you'll need to touch less code in order to implement it.
