In brief: No

Low ferritin is an indication of low iron and may be associates with anemia.
It is not related to thyroid function.

In brief: No

Low ferritin suggests iron-deficiency, which can have some of the same symptoms as low thyroid.
But neither iron levels or ferritin would directly affect the thyroid. Hypothyroidism is usually caused by autoimmunity, where the immune system makes antibodies targeting one's own proteins. If those antibodies target thyroid proteins, hypothyroidism can result.

TIP: If you do have both iron-deficiency and hypothyroidism, be sure to take iron pills at 3-4 hours apart from the thyroid pills.
