Not exactly. Most tv-* variables modify the behavior of some *widget*. In
this case, as written in the documentation:
*The tv-wikilinks variable controls the behaviour of the $link widget.*

The difference between using
\define variablename() ...
and
<$vars variablename="...">
...
</$vars>
is that the \define syntax applies to the whole tiddler in which it occurs,
while the <$vars>...</$vars> syntax has more limited scope.
Also, if a tiddler is tagged with "$:/tags/Macro", then the \define syntax
will automatically be exported as a global macro, whereas the
<$vars>...</$vars> syntax will not.
