Yes, you can do that using htmlRoot parameter. Suppose you have put that file inside folder "script", then you will have to add an optional parameter manually in the script tag inside .html page like below:
<script>
AdobeEdge.loadComposition('htmlRoot', 'EDGE-902451511', {
scaleToFit: "none",
centerStage: "none",
minW: "0",
maxW: "undefined",
width: "550px",
height: "400px",
htmlRoot: "script/"
}, {"dom":{}}, {"dom":{}});
</script>
