No, you can not do this.
Functions within functions have local scope to their containing function, and so cannot be called globally.

To demonstrate:
If you try and call "B" onload instead of "A", you will get an error telling that "B is not defined" - which it isn't at the level you are trying to call it from. It exists only within the scope of function A, and thus can only be called from within function A.

Code:
<html>
<head>
<script type="text/javascript">
function A() {
function B() {
alert('Running function B');
}
alert('Running function A');
}
onload = A;
</script>
</head>
<body>
