If that 160V rating is DC and there is a marked negative terminal then, NO. Most electrolytic caps are polarized meaning the voltage across them must be of the marked polarity.

Non-polarized lytics are more expensive so they aren't designed into something unless absolutely necessary.

There are 3 possible replacement options: non-polarized film cap 250VAC rated with good ripple current (probably the most expensive, probably the longest lasting), AC motor run cap (probably physically bigger than the original and possibly tricky to find space for), find a non-polarized lytic if that value is still made, make a non-polarized lytic out of 2 polarized 160V or higher lytics of double capacitance (10uF) connected in anti-series.
By anti-series I mean take the 2 caps, connect the negatives of both together, tape over the connection so nothing else can connect to it, then the 2 positives connect to the circuit and behave as a single 5uF 160V non-polar lytic.
