OK, so hiding the page #s isn't going to do what you need anyway.
In that case, what you probably need is a macro like the following to convert the TOC to hyperlinks. Do note, though, that hyperlinks don't update the way TOC fields do, so it's probably best to not do the conversion until the document is otherwise finalised.
Code:
Sub ConvertTOC2Hyperlinks()
Dim RngTOC As Range, RngItem As Range, StrBkMkList As String, StrTmp As String, i As Long
With ActiveDocument
With .TablesOfContents(1)
.Update
For i = 2 To .Range.Fields.Count
StrBkMkList = StrBkMkList & "|" & Split(Trim(.Range.Fields(i).Code.Text), " ")(1)
Next
Set RngTOC = .Range
End With
RngTOC.Fields.Unlink
For i = 1 To UBound(Split(StrBkMkList, "|"))
Set RngItem = RngTOC.Paragraphs(i).Range
RngItem.End = RngItem.End - 1
StrTmp = Replace(Split(StrBkMkList, "|")(i), "Toc", "HL")
.Bookmarks.Add Name:=StrTmp, Range:=.Bookmarks(Split(StrBkMkList, "|")(i)).Range
.Bookmarks(Split(StrBkMkList, "|")(i)).Delete
.Hyperlinks.Add Anchor:=RngItem, SubAddress:=.Bookmarks(StrTmp).Range, _
TextToDisplay:=.Bookmarks(StrTmp).Range.Text
Next
End With
End Sub
