Yes: 

Convention: 1. A call that, by partnership agreement, conveys a meaning
other than willingness to play in the denomination named (or in the last
denomination named), or high-card strength or length (three cards or more)
there. However, an agreement as to overall strength does not make a call a
convention.

The 5H bid conveys a meaning other than willingness to play in Hearts.
