No - please don't!  If you have a lawn care program with us, please call us immediately if you see dandelions or common weeds in your lawn and we will come out free of charge between applications to treat them for clients enrolled in a 6 treatment program.  For uncommon weeds, such as perennial Thistle, Nutsedge, Wild Violet, Ground Ivy, and Creeping Charlie, they need a specialized herbicide treatment as they are highly stubborn and prolific, which we can provide pricing for.  Weeds like Thistle should not be pulled, as that will cause the tuberous rhizomatous weeds to produce more weeds.
