The "No" part: Android system has (at least) three partitions - system, cache and data. Data is where applications get installed. Cache is used, well, for caching data and it must be at least the same size as system (because it holds system image when updating over the air).
I don't know for sure how it is partitioned in N1, just guessing: the data partition is 192M, leaving 160M for system and 160M for cache.
The "Yes" part: android partitions on proprietary hardware (and N1 is proprietary hardware, just as G1/ADP1 is) are defined in proprietary boot loader. There is currently no way to change them without going through the risk of having $500 brick on your table.
