The resistance in the trace will cause a couple of problems:
1.) Lower efficiency due to DCR loss
2.) Longer charge time, Voltage taper will start sooner than expected and last longer.
The bq51038 will start voltage taper when it sees 4.2V/4.35V at output pin of IC but voltage at battery will be lower due to voltage drop in trace.
Wider trace with less resistance is better, if possible.
