Yes is the answer. Straight out of the help file...

Find a place using latitude and longitude coordinates (through the MapPoint GUI):

On the Edit menu, click Find, and then click the Lat/Long tab.
In the Latitude box, type the latitude of the place you want to find.
In the Longitude box, type the longitude of the place you want to find.
Click Find.
Note For each latitude and longitude coordinate you find, MapPoint creates a Pushpin on your map. You can add text to the Pushpin balloon and rename it. These Pushpins are automatically stored in a Pushpin set called My Pushpins and saved with your map.

Click OK.

Notes
You can express latitude and longitude coordinates in decimal or DMS (degrees, minutes, and seconds) format.

DMS coordinates can be entered in any of the following ways, where D indicates direction (north, south, east, or west):

dd.mm.ssD

dd:mm:ssD

dd mm ssD

dd°mm'ss"D

If you are entering coordinates in decimal format and the location is south of the equator or west of the Prime Meridian in Greenwich, England, express the latitude or longitude as a negative value; for example, -15.75 degrees latitude and -64.25 degrees longitude.


Alternatively using code (GetLocation):

Dim objApp As New MapPoint.Application
Dim objLoc As MapPoint.Location

'Get the location of Los Angeles, CA, using latitude and longitude
Set objLoc = objApp.ActiveMap.GetLocation(47.75399, -121.97436, 100)
objLoc.GoTo

Not tested the import data wizard, but I expect it will cater for Long/Lat.
