Accepted answer
Since ModType is nullable, it did not return what I was expecting. The code should be...
return seg => seg.ModType == Deleted &&
seg.Line.Segments.Any(segs => segs.ID != seg.ID &&
(segs.ModType != Deleted || segs.ModType == null));
Thanks to all those who replied and gave comments and suggestions!

Instead of Any(), use Where(), which will return you an IEnumerable object. Like Jon says, Any() returns a boolean.

I'd think it would be something like:
return s => from segment in s.Line.Segments
where segment.ModType == Deleted
&& segment.Line.Segments.Any(segs => segs.ModType != Deleted)
select segment
