I do not think that you can do this in versions prior to 1.10. However, in 1.10 you can do the following:
Declare a component template and yield
<script type="text/x-handlebars" id="components/table-notes">
{{#each notes as |note|}}
{{ yield note }}
{{/each}}
</script>
And also declare in the template using components called a variable noteas follows:
<script type="text/x-handlebars" data-template-name="index">
{{#table-notes notes=model.notes as |note|}}
<h3>{{ note }}</h3>
{{/table-notes}}
</script>
