[DBZ]Was there anything preventing Captain Ginyu from attempting to switch bodies with Frieza?

And why would Frieza keep someone with such a dangerous power so close? Did he know about it?

For a start, he was loyal so he had little desire to do body switch. He was very satisfied as top henchman.

For a second, Freiza is much more powerful and so it would be harder for him to do it, and Freiza may well just kill him for his impertinance or block it.
