It is a 'fair' entry if the rules allow it. Most contests require you list all stitchers on the quilt. I don't know if judges weight it differently if it was all done by one person or not, but it is generally disclosed. Perhaps you should look for shows that only allow single stitchers- they are out there.
For the record- the quilt that won Best of Show at the AQS show in Des Moines this weekend (a $10,000 prize) was quilted on a domestic machine. (And they have a special category of "Best Machine Worksmanship" that is for a domestic machine- it is a $5,000 prize.) You don't need to be able to longarm to make amazing quilts.
