Will the metal cutting disc on a Dremel actually cut through metal?

Yeah it will but, don't git to aggresive.  Why?, you can set the dremel on fire, been there, done that.  Bought a roto zip, by boush, model rz2, all the dremel stuff will fit it.  Sweet tool, git as aggresive as you want, no fire, fire bad

You can set anything on fire.

Hey - got on the dremel site to check out the Bosch RZ2 compatability and look what ist says at the bottom of the web page:

I did not know that.

cutting a few tabs off should not require a 4.5" angle grinder.  really not a big deal.  you should be able to get them off with 1 or 2 of the larger fiber reinforced disks.  just wind the dremel up to ten and cut slow, be careful to keep the blade straight once into the bracket, touching the sides will ruin the disk very quickly.  best bet is to draw a line with the disk right at the weld then work the disk back and forth over the line until you're through.  once the tabs are off you can clean them up with a sanding drum or cylindrical stone.  just take your time and it should be no problem.  5-15 minutes per tab depending on how clean you take the welds down to. 

use these, #456 1-1/2"fiber glass reinforced cut-off disk

and don't forget safety glasses, if (when) the disk comes apart fragments fly everywhere.   

+1 on everything aaronb said here, I used a dremel on a few different pieces (including stainless steel pieces on the exhaust). Just get the fiber discs and don't push too hard (have some patience) and they last longer than you would think.
