Removal of "as to"

"Not restricted location or area of concern" is not grammatical.

A peripatetic question?

Sorry! I meant "not restricted to location..."

Thanks, InfraBlue!

1a: not restricted as to location or area of concern. b : capable of being shifted from place to place : mobile. 2 : inclined to ramble or stray a roving fancy. roving. Definition of roving (Entry 2 of 2)

I meant if "as" can be removed?

Hence, "not restricted to location..."

"As to" here means "in regard to," or better "for example," so the meaning would be different if you were to say "not restricted to location or area of concern."
