Is a 4 year old child too young for the Trail A Bike?

No - that generally should be fine. I think we started at about age 5. The
great advantage of these contraptions is that you can range much further
with a kid on a trail-a-bike than you can with a kid on his or her own
bike - and you don't have to invest in a tandem.

Here's a story from a while back about such a ride:
