is it possible that the clients connected to that AP could fail over to another AP
That depends on the wireless clients.
Wireless client make the ultimate/final decision which AP to join.
Old wireless drivers are infamously known for making the worst decision about roaming.

impact network performance for all the clients connected to that single AP?
I had a single 1142 service 98 wireless clients. Daily. No complaints.
The performance of the 1142 is a shadow of what the 4800 can do. Bigger CPU, memory, FRA and mGIG. FRA and mGIG play an important role to minimize congestion.
