Yes, you could put in a manual page break where you want to start the second page. This is going to look not that great and you could potentially end up with three pages rather than two.
A better method would be to change one or more of the following:
- Line spacing - space between lines within a paragraph
- Paragraph spacing - space between paragraphs
- Font size
- Narrow your paragraph indents to give the appearance of wider margins.
All of the above can likely be done by modifying a couple of styles.
