No, actually, it's more likely to evaluate to false in that case.
<cfset myvar = "foo">
<cfif IsDefined("myvar")> <!--- this will evaluate to true --->
true
<cfelse>
false
</cfif>
<cfif IsDefined(myvar)> <!--- this will evaluate myvar to foo, then look for
a variable named foo --->
true
<cfelse>
false
</cfif>
