Applications may do so. The Unicode standard does not define the meaning of NBH or other C1 Controls, see
http://unicode.org/uni2book/ch13.pdf
There is also the NBSP (No-break Space: U00A0), which I think has to be mapped to the space character in fonts, that glues two letters together by a space.
NBSP has defined semantics in Unicode, but it can be implemented in different ways (it could have a glyph of its own).
NBH is more appropriate for use within ISO-8859-1 characters than ZWNJ, because the latter is double-byte.
ZWNJ is not an ISO-8859-1 character at all. In Unicode, it is a control character that prevents the use of a ligature. The character to prevent line breaking, with no other effect, is ZERO-WIDTH NO-BREAK SPACE.
Whether NBH works at all really depends on the application, and I would not expect applications to support it in practice, irrespective of character encodings.
