I'm using SQL Server 2008 Express Edition. Just wondering is it valid for me to assign non-primary key column from the primary key table in the Foreign Key Relationship Dialog? Will it lead to any problem?

No problem. There's nothing special about a "primary" key. Any other candidate key will do just as well.
