You could use a field coded along the lines of:
{IF{ TOC \c "Figure" }= "?No*" "" "Table of Figures¶
{ TOC \c "Figure" }"}
where the ¶ is a real paragraph break, formatted in whatever Style you want for the 'Table of Figures' heading (you can change the text for that too, if you wish).

Note: The field brace pairs (ie '{ }') for the above example are all created in the document itself, via Ctrl-F9 (Cmd-F9 on a Mac); you can't simply type them or copy & paste them from this message. Nor is it practicable to add them via any of the standard Word dialogues.
