It is true that it is a little more nuanced than "has no syntax". The core of the language has very little syntax relative to many of the more popular languages but it still does have some syntax. The confusion also arises because often the syntax it does have looks just the same as function invocation. "or" is syntax whereas "+" is not but they both look the same in invocation. (or fu bar) and (+ 1 2) but "or" is short circuiting and "+" is not. "or" is syntax but it doesn't look like the syntax a lot of people are used to.

In fact, if you use scheme extensively you will probably use more syntax than most languages. Scheme and other lisps are very good at allowing you to create new syntax which is very helpful in creating DSLs which you will run across a lot in scheme libraries and the SRFIs.
