The junky old Win8.1 tablet I picked up uses the same CPU as my Linx1010 (Z3735) but only has 1GB Ram and 16GB flash (most of which is used 
) but there was enough to install SDR#.
This old link shows it running SDR# with a USB DVB-T dongle:
So I think it may well be fine. You can pick up keyboard-less 10in Linx units (reconditioned) for about £80 on a “well known Internet marketplace”.
