In brief: No
No, pica is the ingestion of non-food, usually non-biological material.
Finger nail biting is usually associated with anxiety or obsessive-compulsive disorder (not always). Cuticle biting often results when a person has dry skin or atopic dermatitis, so those conditions should be ruled out when evaluating someone who bites his or her cuticles. Hand-washing and allergies make it worse.
