Possibly, but even mother boards supporting 32MB would be rare. Perhaps on "DX3"?
As for a new computer and price - it was like $1000 to get AMD 486DX2-80 with 4MB RAM in '95...
So this depends if it was a 72 pin DIMM board. I don't think you could get there (easily?) on a 30 pin board, but 72 may have had native support for 64 out of the box.
I upgraded a ~1992 Dell 486 DX2 to 36MB (original 4MB + 32MB...or was it a pair of 16MB sticks? hard to remember) around 1997 or so.
